IPC: H02H7/085
Filed: 1959-01-09
Abstract: 863,291. Protective cut-out arrangements; control of A.C. motors. ALLIS-CHALMERS MANUFACTURING CO. Jan. 9, 1959, No. 925/59. Classes 38 (3) and 38 (5). A system, e.g. for the control and protection of a synchronous motor, has circuit-breaker means, a first thermal device connected so that a first current will heat it when the circuitbreaker means are closed and operative to cause the opening of the circuit-breaker means when heated to a predetermined temperature, means operated by the circuit-breaker means (when opened by the operation of the thermal device) to cause a second lower current to delay the cooling of the thermal device, and a second thermal device for controlling the ambient temperature around the first thermal device. In the system shown, the closing of a " start " switch 60 causes the energizing of the closing coil 61 of a circuit-breaker 22 which closes to energize the motor 16 and to start a timing device 48. After a predetermined time, the device 48 closes contacts 53 to complete the circuit for energizing the closing coil 70 of a circuit-breaker 23 which closes to short-circuit a starting reactor 21 and at its auxiliary contacts h completes a circuit through auxiliary contacts f of a field contactor 28 to cause the " first " current to flow through a heater coil 38 in series with a resistor 37. The heater coil 38 heats a bimetallic element 39 of the first thermal device so that should the element 39 be heated to the predetermined temperature before the starting operation of the motor 16 is completed by the operation of the contactor 28, then the element 39 closes contacts 40, 41 to trip the circuit-breakers 22, 23. When the circuitbreaker 22 is tripped open, it completes at its auxiliary contacts h a circuit through part of a resistor 42 and the closed contacts 40, 41 to energize the heater coil 38 with the " second " lower current to delay the cooling of the bimetal element 39 to simulate the cooling of the squirrel cage of the motor 16 when motionless. If on the other hand the starting operation is completed before the thermal device operates, then the contactor 28 opens its auxiliary contacts f to remove the short-circuit from the resistor 42 (auxiliary contacts h of circuitbreaker 23 being closed) so that the heater 38 is energized through all the resistor 42 and the element 39 is heated by a " third " lower current to co-ordinate the cooling of the element 39 with that of the squirrel cage of the motor when running. The second thermal device comprises a bimetallic element 43 operating contacts 44, 45 in series with heater elements 46, 46<SP>1</SP> and by cyclic operation maintains a constant temperature in the housing 47 containing the first thermal device. Fig. 5 (not shown) illustrates a modified system in which the heating of the element 39 starts as soon as the circuit-breaker 22 closes.
